What are the common sequelae of Baylisascaris procyonis infection in humans?

• A. Visceral, ocular, or neural larval migrans.
• B. Skin rash and itching.
• C. Gastrointestinal bleeding.
• D. Renal failure.

Answer: (A)

The main concept here is that Baylisascaris procyonis infection in humans causes migrating larvae that can affect multiple tissues, producing visceral, ocular, or neural larval migrans. Humans are accidental hosts, and the larvae can travel through various organs rather than staying localized. This yields a spectrum of disease, with visceral involvement affecting internal organs, ocular involvement impairing vision, and neural involvement causing severe brain or spinal cord disease. Among these, neural larval migrans can be especially severe and life-threatening, which is why the trio of visceral, ocular, and neural migrans is the characteristic and most important way this infection presents in humans. The other options don’t fit because they describe manifestations not typical of Baylisascaris procyonis infection. Skin rash and itching, gastrointestinal bleeding, or renal failure are not the hallmark sequelae of this parasite, whose hallmark complication is tissue migration leading to visceral, ocular, or neural involvement.
